I lived in Germany. I also lived in Netherlands, England and Scotland (yes there is a difference).
There are pros and cons to every country.
I loved Germany and the Netherlands. I found the people friendly, helpful and polite for the most part.
But there are downsides too. Germany doesn't integrate immigrants well, especially if they're not white European ethnicity. There are lots of rules and regulations and they are adhered to. If they're not there are high fines regarding garden conditions, bin management etc.
The houses are bigger because Germany is bigger. They have more land. The reason English is spoken so widely around the world and the U.K. Is appalling in its approach to learning other languages is arrogance both historical and modern. Historically we invaded and pillaged many a country and enforced English language upon the natives then having done so we continued not to bother to learn their languages as 'well they all speak English anyway' 
I have friends and family who are living/have lived in :
France
Belgium
Italy
Australia
America
Canada
India
Pakistan
Ghana
Sierra Leone...
The British really don't know they're born a lot of the time.
I hate the current govt and what they are doing to the U.K. And especially the nhs and hope that the GE leads to a temperance if not complete halt to this.
